Fraud company which doesn't pay part time employees - Senior Backend Engineer bei Code Vyasa: Mitarbeiterbewertung

Codevyasa committed a fraud with me by not paying me for my work. I worked at the company as a software engineer in a part-time contractual position for a client. I wanted to leave the company during probation period and Code Vyasa promptly took back the laptop and did not ask me to serve the notice period. Instead, they asked me to work for a few more days (for which they said I'd be paid) until which they find a replacement for me so that client work is not affected. I had a lengthy discussion about this. I continued for a few more days as he said and gave back the laptop only to find out that I didn't receive my pay for the days that I'd worked. The senior management said that they pay probation employees a little late but even after multiple emails, they did not pay me and stopped responding to my emails too.
